To all whom it may concern: 1

Be it known that I, THOMAS H. HoADLnY, a citizen of the United States, residingat Gladbrook, in the county of Tama and State of Iowa, have invented certain new and use ful Improvements in Railroad-Ties; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to Which it appertains tomake and use the same.

. My invention relatesto new and useful. improvements in metallic rail t1es and has. for its primary ob ect to generally improve and simplify the construction of such devices so as to render them more reliable and efficient in supporting rails, inexpensive to manufacture and durable.

An object of importance is to provide a rail tie of the character described that possesses the resiliency of a wooden tie in combination with the durability and other indestructibleproperties of the metallic tle.

The above and additional objects are accomplished by such means as are illustrated in the accompanying drawings, described in the following specification and then more particularly pointed out as claimed.

With reference to the drawings, wherein I have illustrated the preferred embodiment of my invention as it is reduced to practice and throughout the several views of which similar reference numerals designate corre sponding parts,

Figure 1 is a perspective view of my 1mproved tie with the rails removed. F1g. is a fragmentary longitudinal sectional view taken through one of my ties showing the rail in position. Fig. 3 is a transverse sectional view taken through the tie at a point adjacent to one end, and Fig. 4 is a detailed perspective view of one of the wedgeplates.

Referring to the drawings 1 designates as an entirety a metallic base plate of the tie which is provided upon its longitudinal edges with upwardly and inwardly inclined sides 2 which sides extend the full length of the plate 1 and adjacent to each end are recessed as at 3 for a purpose to be later more fully described.

Mounted between the side walls 2 at the end of the tie are wedge shaped or dovetail rail supporting blocks 4 which are formed of wood or some other suitable resilient material and of just sufficient size to adequately support the rails. The rail bases are designed to engage upon 'blocks 4 at points where the recesses 3 are formed so that the rails will be allowed to sinkwithout engaging] thesides 2. To hold the blocks 4 holes 4 are provided. These bolts pass through the side 2 and engage the inner ends of the blocks 4.

Adjacent each end of the tie is formed a pair of transverse rectangular holding straps 5 and 5. The straps 5 are formed integral with; the sides 2 and engage upon the upper faces of the blocks 4. These straps are sufficiently spaced to permit the rails to be placed upon the blocks 4 between the straps and to have the spikes 6 for securing the rails inserted between the bases of the rails and the straps.

A filler or body of concrete 7 or some other suitable plastic material is placed within the tie between the opposed inner ends of the blocks 4 and said filler of concrete or the like has its upper face flush with the sides of the tie. The filler 7 is reinforced by rods 7 which are embedded therein and which extend longitudinally thereof. The straps 5 extend inwardly beyond the inner ends of the blocks 4 so as to overlie the filler 7 and thereby prevent it from having any vertical movement with relation to the tie. At points intermediate the straps 5 the tie is provided with straps 7 which also prevent the filler from having any vertical movement with relation to the tie. Should the blocks 4 become loose as a result of shrinkage or wear, they may be tightened up by means of the Wedge plates 8. In practice the Wedge plates 8 are inserted beneath the blocks 4, bringing their sides in firm engagement with the inner surfaces of the sides 2 and their tops in firm engagement with the under sides of the straps 5 and 5 The blocks 4 are pre vented upward longitudinal and lateral movement by the side walls 2 and the particular arrangement of the straps 5.

It will be readily seen that my improved rail tie will prove extremely durable and provides for a great amount of track resiliency. The parts are of similar construction and may be readily assembled and disassembled for renewal if desired.

In practice, I have found that the form of my invention, illustrated in the drawings and referred to in the above description, as the preferred embodiment, is the most agalnst. outward horizontal displacement tailed to cooperate with the inclined side" Walls and supporting straps engaging the) tops of the blocks and formed integral with the sides.

2. A rail tie consisting of a rectangular base plate, upstanding inwardly inclined sidewalls formed on the longitudinal edges of the base plates resilient rail supporting blocks mounted upon the base plate between the side walls and having upwardly and inwardly inclined side faces to cooperate with the side Walls, straps formed integral with the" side walls adjacentto each end and arranged in pairsand extending trans: versely of the" tie in engagement with the O'op'ies of thisp'atent my 15's olit ained fbr five tears each,

tops of the rail supporting blocks and being spaced from one another .a plastic filler mounted between the sidewalls and inner ends of the blocks, and said side walls being recessed at their upper edges at points between said straps.

A rail tie consisting of a rectangular base plate, upstanding inwardly inclined I side walls formed on the longitudinal edges of the base plate; resilient rail supporting blocks mounted upon the base plate between the side walls and having upwardly and inweirdly inclined side faces to cooperate with the side walls, straps formed integral with the side walls adjacent to each end and arranged in pairs and extending transversely of the tie in engagement with the topsof the rail supporting blocks and being spaced from one another, and a plastic filler mounted between the side walls andinner Zends of the blocks, said side walls being recessed at their upper edges at points be- In testimony whereof l afiiX my signature in presence of two witnesses.
